Unofficial RISC OS Filetypes List

This version of the file was generated on 2019-02-22 at 12:52:53 UTC
and lists all the registered filetypes (as published by RISCOS Ltd),
and also all the unregistered ones that have not been marked
as deprecated.

Updates

Sadly, nobody has time to edit the official filetype list for
public consumption. They would have to remove allocations for products
which have not been announced to the public yet, hence this list.

Overview

000-0FF

Personal usage (non-distributed)

100-3FF

Non-commercial distributed software

400-9FF

Commercial Software

A00-AFF

Acornsoft and other commercial software

B00-DFF

Commercial software

E00-FFF

Acorn

The minimum requirement for a valid allocation is that double-clicking
the file loads an application and does something meaningful with it.
Use existing file formats (not just within the Acorn world), and make
data interchange as painless as possible. If your software is going
to be distributed, get an allocated filetype to avoid clashes.

Key

The list has one line for each different use of a filetype.
Each line has the format:

HEX S NAME DESCRIPTION; APP (ORIGIN); APP (ORIGIN).. EXTENSION

HEX Three hexadecimal digits

S Status

R => This type is registered with Acorn/Pineapple

D => deprecated - a registered or newer type exists

NAME The short name for the type (File$Type_XXX)

DESCRIPTION The kind of data in files of this type

APP Software which handles this type

ORIGIN The originator (author or company) of the software

EXTENSION Common filename extensions used elsewhere and MIME content types
